The Glaciated High Plateau Section consists of broad to narrow, rounded to relatively flat, elongate uplands separated in most places from the adjacent Glaciated Low Plateau Section by a steep-sloped, well defined escarpment. These uplands are dissected by steep to shallow valleys. Each elongate upland corresponds to a syncline whose axis is in the approximate center of the up-land. The Deep Valleys Section occurs in north-central northeastern Pennsylvania in parts of Bradford, Columbia, Luzerne, Lycoming, McKean, Potter, Sullivan, Tioga, and Wyoming counties.

Excellent routes through the Section are US Route 15 from Trout Run to Lawrenceville. This route passes back and forth between the Glaciated High Plateau Section and the adjacent Glaciated Low Plateau Section thus passing through contrasting topography and providing a real appreciation for the boundary between the two Sections. Other Pennsylvania Routes that allow good looks at the Section are: 487 from Red Rock to Dushore; 87 from Loyalsock to Dushore; 14 from Trout Run to Grover; and 49 from Elkland to Gold. Other good routes are: US Route 6 from Wellsboro to Galeton; US Route 220 from Muncy Valley to Monroeton; and Pennsylvania Route 287 from English Center to Tioga.
